Subject: problems with installing the ruby libnet module

Hi,
I tried to install the Ruby Libnet module from 
http://rubyforge.org/projects/ruby-libnet/ . So I downloaded it with svn 
update to my local machine and wanted to install it with:ruby extconf.rb .
But this just gives me an error:

 >>> ruby extconf.rb

checking for main() in -lnet... no
Dependency failed
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Provided configuration options:
         --with-opt-dir
         --without-opt-dir
         --with-opt-include
         --without-opt-include=${opt-dir}/include
         --with-opt-lib
         --without-opt-lib=${opt-dir}/lib
         --with-make-prog
         --without-make-prog
         --srcdir=.
         --curdir
         --ruby=/usr/bin/ruby1.8
         --with-netlib
         --without-netlib


 >>> cat mkmf.log

have_library: checking for main() in -lnet... -------------------- no

so it seems I'm missing the lnet library ?!?!? But what is this and any 
idea how to install it on linux (ubuntu) ?
